RESUMO
In December 2019, a new Coronavirus (SARS-CoV-2) emerged in China, causing the pandemic disease COVID-19. The clinical presentation is variable, but the predominant symptoms are those of the upper respiratory tract. AIM: The aim of the current study is to describe the incidence and type of the gastrointestinal injury (GI) in COVID-19, as well as their prognostic value. MATERIALS AND METHODS: We conducted a coincidental search on this topic in PubMed, Web of Science and EMBASE. We also followed a group of 31 Bulgarian COVID-19 patients throughout the course of their disease and analyzed their symptoms (catarrhal and other) and outcome. RESULTS: The publications concerning our survey followed a total of 1509 COVID-19 patients. In the Bulgarian cohort, only 14 from the 31 patients were laboratory-confirmed COVID-19 cases. Approximately 1/3 of the infected individuals presented with GI. In some patients this was the first, or only, symptom of the disease. It was also indicative of a more severe disease course. CONCLUSION: GI may be an important symptom and prognostic factor in COVID-19. Therefore, patients with acute gastrointestinal symptoms must be actively tested for SARS-CoV-2.

During the novel coronavirus pandemic, organ transplant recipients represent a frail susceptible category due to long-term immunosuppressive therapy. For this reason, clinical manifestations may differ from general population and different treatment approaches may be needed. We present the case of a 36-year-old kidney-transplanted woman affected by Senior-Loken syndrome diagnosed with COVID-19 pneumonia after a contact with her positive mother. Initial symptoms were fatigue, dry cough, and coryza; she never had fever nor oxygen supplementation. Hydroxychloroquine and lopinavir/ritonavir were started, and the antiviral drug was replaced with darunavir/cobicistat after 2 days for diarrhea. Immunosuppressant levels were closely monitored, and we observed very high tacrolimus trough levels despite initial dose reduction. The patient was left with steroid therapy alone. The peculiarity of clinical presentation and the management difficulties represent the flagship of our case report. We stress the need for guidelines in transplant recipients with COVID-19 infection with particular regard to the management of therapy.

Exposure to parental separation or divorce during childhood has been associated with an increased risk for physical morbidity during adulthood. Here we tested the hypothesis that this association is primarily attributable to separated parents who do not communicate with each other. We also examined whether early exposure to separated parents in conflict is associated with greater viral-induced inflammatory response in adulthood and in turn with increased susceptibility to viral-induced upper respiratory disease. After assessment of their parents' relationship during their childhood, 201 healthy volunteers, age 18-55 y, were quarantined, experimentally exposed to a virus that causes a common cold, and monitored for 5 d for the development of a respiratory illness. Monitoring included daily assessments of viral-specific infection, objective markers of illness, and local production of proinflammatory cytokines. Adults whose parents lived apart and never spoke during their childhood were more than three times as likely to develop a cold when exposed to the upper respiratory virus than adults from intact families. Conversely, individuals whose parents were separated but communicated with each other showed no increase in risk compared with those from intact families. These differences persisted in analyses adjusted for potentially confounding variables (demographics, current socioeconomic status, body mass index, season, baseline immunity to the challenge virus, affectivity, and childhood socioeconomic status). Mediation analyses were consistent with the hypothesis that greater susceptibility to respiratory infectious illness among the offspring of noncommunicating parents was attributable to a greater local proinflammatory response to infection.

International case definitions recommended by the Centers for Disease Control and Prevention (CDC), the European Centre for Disease Prevention and Control (ECDC), and the World Health Organization (WHO) are commonly used for influenza surveillance. We evaluated clinical factors associated with the laboratory-confirmed diagnosis of influenza and the performance of these influenza case definitions by using a complete dataset of 14,994 patients with acute respiratory infection (ARI) from whom a specimen was collected between August 2009 and April 2014 by the Groupes Régionaux d'Observation de la Grippe (GROG), a French national influenza surveillance network. Cough and fever ≥ 39 °C most accurately predicted an influenza infection in all age groups. Several other symptoms were associated with an increased risk of influenza (headache, weakness, myalgia, coryza) or decreased risk (adenopathy, pharyngitis, shortness of breath, otitis/otalgia, bronchitis/ bronchiolitis), but not throughout all age groups. The WHO case definition for influenza-like illness (ILI) had the highest specificity with 21.4%, while the ECDC ILI case definition had the highest sensitivity with 96.1%. The diagnosis among children younger than 5 years remains challenging. The study compared the performance of clinical influenza definitions based on outpatient surveillance and will contribute to improving the comparability of data shared at international level.

OBJECTIVE: Loneliness is a well-established risk factor for poor physical health. Much less is known about how loneliness affects patient-reported outcomes (PROs), such as somatic symptoms, which are increasingly important for guiding symptom management and assessing quality of patient care. The current study investigates whether (a) loneliness and social isolation predict cold symptoms independent of each other, and (b) whether loneliness is a more robust risk factor than objective social isolation for experiencing cold symptoms. METHOD: As part of a larger parent study, 213 healthy participants completed the Short Loneliness Scale (LON) and the Social Network Index (SNI) at baseline. They were given nasal drops containing rhinovirus 39 (RV39; i.e., a common cold virus), then quarantined for 5 days during which they reported on subjective cold symptoms in addition to being monitored for objective indicators of infection. Data from 160 of the participants (who were infected with the virus) were used in the present analyses. RESULTS: A hierarchical multiple regression revealed that baseline loneliness predicted self-reported cold symptoms over time (assessed via area under the curve), over and above demographic variables, season of participation, and depressive affect. Interestingly, social network size and diversity did not predict cold symptoms. CONCLUSIONS: These findings suggest that the perception of loneliness is more closely linked to self-reported illness symptoms than objectively measured social isolation. Assessing psychosocial factors such as loneliness when treating and evaluating the common cold could contribute to health care practitioners' understanding of their patients' experiences with acute illness.

OBJECTIVE: The aim was to examine whether trait positive and negative affect (PA, NA) moderate the stress-buffering effect of perceived social support on risk for developing a cold subsequent to being exposed to a virus that causes mild upper respiratory illness. METHOD: Analyses were based on archival data from 694 healthy adults (Mage = 31.0 years, SD = 10.7 years; 49.0% female; 64.6% Caucasian). Perceived social support and perceived stress were assessed by self-report questionnaire and trait affect by aggregating responses to daily mood items administered by telephone interview across several days. Subsequently, participants were exposed to a virus that causes the common cold and monitored for 5 days for clinical illness (infection + objective signs of illness). RESULTS: Two 3-way interactions emerged-Support × Stress × PA and Support × Stress × NA. The nature of these effects was such that among persons with high trait PA or low trait NA, greater social support attenuated the risk of developing a cold when under high but not low perceived stress; this stress-buffering effect did not emerge among persons with low trait PA or high trait NA. CONCLUSIONS: Dispositional affect might be used to identify individuals who may be most responsive to social support and support-based interventions.

OBJECTIVES: To describe the home environment in terms of housing conditions and their association with child health in a disadvantaged immigrant population. DESIGN: A cross-sectional observational study. SETTING: Enrolment took place during 2010-2011 in Rosengård, Malmö, Sweden. PARTICIPANTS: Children aged 0-13 years in 2 study neighbourhoods were recruited from local health records and from schools. 359 children participated, with a participation rate of 40%. Data on health, lifestyle and apartment characteristics from questionnaire-led interviews with the mothers of the children were obtained together with data from home inspections carried out by trained health communicators. OUTCOME MEASURES: Logistic regression analysis was used to estimate ORs for various health outcomes, adjusted for demographic information and lifestyle factors. RESULTS: The housing conditions were very poor, especially in one of the study neighbourhoods where 67% of the apartments had been sanitised of cockroaches, 27% were infested with cockroaches and 40% had a visible mould. The association between housing conditions and health was mostly inconclusive, but there were statistically significant associations between current asthma and dampness (OR=4.1, 95% CI 1.7 to 9.9), between asthma medication and dampness (OR=2.8, 95% CI 1.2 to 6.4), and between mould and headache (OR=4.2, 95% CI 1.2 to 14.8). The presence of cockroaches was associated with emergency care visits, with colds, with headache and with difficulty falling asleep, and worse general health was associated with mould and presence of cockroaches. CONCLUSIONS: The associations between dampness and asthma, and the association between mould and headache, are in line with current knowledge. The presence of cockroaches seemed to be associated with various outcomes, including those related to mental well-being, which is less described in the literature. The results of the present study are hypothesis generating and provide strong incentives for future studies in this study population.

The immunosuppressive effects of glucocorticoids (GCs) are well-established. However, whether the net effect of GC-elicited alterations in immune function is sufficient to influence a clinically relevant outcome in healthy adults has yet to be shown. The aim of the present study was to investigate whether inter-individual differences in basal salivary cortisol production are associated with increased risk and severity of infection and subsequent illness following experimental exposure to a virus that causes the common cold. The present analyses combine archival data from three viral-challenge studies. Participants were 608 healthy adults, aged 18 to 55 years (49.2% female; 65.8% white), who each completed a three-day saliva collection protocol; was subsequently exposed to a virus that causes the common cold; and monitored for 5 days for objective signs of infection (presence of challenge virus in nasal secretions) and clinical illness (mucus weight, mucociliary clearance time). Basal cortisol production (operationalized as the calculated area-under-the-curve averaged across the 3 days) showed a graded association with infection risk, with those producing higher levels of cortisol being at greater risk. Cortisol also showed a continuous association with duration of viral shedding, an indicator of viral replication and continuing infection, such that higher cortisol concentrations predicted more days of shedding. Cortisol was not, however, related to severity of objective illness. These findings are the first to demonstrate in healthy adults an association between basal cortisol production and an objectively measured and clinically relevant infectious disease outcome.

GOALS: We designed this study to evaluate the efficacy of spleen salvage during distal pancreatectomy for patients with benign and borderline malignant tumors. BACKGROUND: Despite the emphasis on its role, the spleen has commonly been removed in distal pancreatectomy. STUDY: From January 2005 to July 2009, 82 patients underwent distal pancreatectomy with splenectomy (DPS) and 78 patients underwent spleen-preserving distal pancreatectomy (SPDP). Medical records were retrospectively reviewed. RESULTS: There were no significant differences in demographics, final diagnoses, estimated blood loss, intraoperative transfusion, and operative time between the 2 groups. More perioperative complications occurred in the DPS group than in the SPDP group (P=0.0344). Consequently, postoperative hospital stay was significantly shorter in the SPDP group than in the DPS group (P=0.0273). In the follow-up survey, episodes of common cold or flu were apparently more frequent in the DPS group (P=0.047). More patients in the DPS group felt fatigue (P=0.0481) and poor health condition (P=0.0371). Less newly developed (P=0.0193) and aggravated diabetes mellitus (P=0.0361) were also observed in the SPDP group. Platelet counts on postoperative day (POD) 5, hemoglobin on POD 3, WBC counts, and CRP level on POD 2 were significantly higher in the DPS group than in the SPDP group and these differences continued to be significant for months after surgery. CONCLUSIONS: In addition to frequent higher grade complications, prolonged hospital stays, and severe hematological abnormalities, DPS seemed to result in poor health condition based on the follow-up survey. Even an effort to preserve an adult spleen in distal pancreatectomy is worthwhile.

Rhinosinusitis (RS) is an inflammatory disorder of the mucous membranes of the nose and paranasal sinuses, which are almost always affected concurrently. The EPOS2012 position paper initiated by the European Rhinologic Society and the European Academy of Allergy and Clinical Immunology is a recent comprehensive source on this common disease affecting approximately 20% of the population worldwide. Inflammation, not infection, is considered the cornerstone of RS, which is considered a temporal and pathophysiologic disease continuum with various subtypes. Acute rhinosinusitis is diagnosed, if typical symptoms last less than 12 weeks. It affects approximately 10% of the European population. Acute RS is further subdivided into acute viral, acute postviral and acute bacterial RS. Acute viral RS lasts less than 10 days with decreasing symptom intensity, while acute postviral RS is characterized by longer duration or a sudden increase of symptom severity around the 5th day ('double sickening'). Acute bacterial RS is assumed if 3 of the following 5 criteria are additionally met: Discoloured discharge (with unilateral predominance), severe local pain (with unilateral predominance), fever (>38ºC), elevated ESR/CRP, and 'double-sickening'. For the treatment of acute viral RS, nasal saline irrigations and OTC cold remedies are advised. In acute postviral RS, additional topical steroids are suggested. Advantages and disadvantages of antibiotic treatment in acute bacterial RS are detailed. Overall, the new EPOS position paper infers a reorientation in this area of high medical, pharmaceutical and economic relevance.

OBJECTIVE: To determine sleep deprivation and its consequences on doctors in tertiary care hospitals. METHODS: The cross-sectional study was conducted from February to May 2012 and comprised house officers and postgraduate trainees at 4 public and 1 private tertiary care hospitals in Karachi. The subjects were posted in wards, out-patient departments and emergencies. A proforma was designed with questions about duration of duty hours, sleep deprivation and its effects on quality of performance, and presence of anxiety, depression, medical errors, frequent cold and infections, accidents, weight changes, and insomnia. Duration of 1 hour was given to fill the proforma. SPSS 20 was used for data analysis. RESULT: The study comprised 364 subjects: 187 (51.37%) house officers and 177 (48.62%) postgraduate trainees. There were 274 (75.27%) females and 90 (24.72%) males. Of those who admitted to being sleep deprived (287; 78.84%), also complained of generalised weakness and poor performance (n = 115; 40%), anxiety (n = 110; 38%), frequent cold and infections (n = 107; 37%), personality changes (n = 93; 32%), depression (n = 86; 30%), risk of accidents (n = 68; 23.7%), medical errors (n = 58; 20%) and insomnia (n = 52; 18%). CONCLUSION: Having to spend 80-90 hours per week in hospitals causes sleep deprivation and negative work performance among doctors. Also, there is anxiety, depression and risk of accidents in their personal lives.

BACKGROUND: Chronic catarrh is commonly encountered in primary care, but often presents a quandary to the clinician because the history of postnasal or pharyngeal mucus build-up is frequently at odds with the absence of physical findings. As with certain other medically mysterious syndromes, the value of often costly investigation remains unclear in both the primary and the secondary care settings. Indeed, investigation may reassure the physician more than the patient (1) and could even prove counter-productive through reinforcement of the patient's belief about the presence of significant pathology (2). AIM: To establish the benefit of referral of chronic catarrh patients for specialist investigation. DESIGN: A cross-sectional survey. SETTING: A total of 138 patients referred to secondary care with chronic catarrh, postnasal drip or throat clearing in the north of England. METHODS: Subjects completed three disease-specific symptom-scoring questionnaires (RSI, SNOT-20 and GETS). Investigations performed were saccharin clearance time, nasendoscopy, skinprick allergy testing and CT of sinuses. Results were compared with published values. RESULTS: Catarrh patients scored highly on all three symptom questionnaires. Nasendoscopy was normal in 70% of patients, with the remainder demonstrating mostly simple mucus (20%), lymphoid tissue (6%) or mucopus (2%). Only 6 of the 136 patients tested had a prolonged saccharin clearance time greater than 30 min. The mean score of the 63 sinus CT scans obtained was 2.6 (normal range = 0-5). Of patients undergoing skinprick testing (n = 45), 30% reacted to one or more inhaled allergen. No rhinological investigation yielded results above that expected in the general population. CONCLUSION: Chronic catarrh appears to be related more to pharyngeal symptom awareness than to pathological postnasal drip or mucus over-production. Rhinological investigations have a limited role in the management of chronic catarrh patients. The principal outcome of ENT referral is likely to be reassurance and direction towards patient self-help information.

BACKGROUND: Acute psychological stress induced by academic exams is associated with dysregulated gastrointestinal and immune function. OBJECTIVE: We examined whether supplementation with galactooligosaccharides reduced gastrointestinal dysfunction and the percentage of days with cold or flu in academically stressed undergraduate students. DESIGN: In a randomized, double-blind study, subjects (n = 427) received 0, 2.5, or 5.0 g galactooligosaccharides for 8 wk around the time of fall final exams. Levels of stress and cold or flu symptom intensity (SI; 0 = not experiencing to 3 = severe) were recorded daily. The SI from 9 cold or flu symptoms was summed with 1 d of cold or flu defined as a sum >6. The Gastrointestinal Symptom Response Scale was completed weekly. RESULTS: Stress was positively related to diarrhea, indigestion, and reflux syndromes and with abdominal pain, average daily cold or flu SI score, and the percentage of days with cold or flu. Gastrointestinal symptom scores for diarrhea (P = 0.0298), constipation (P = 0.0342), abdominal pain (P = 0.0058), and indigestion (P = 0.0003) syndromes were lower after galactooligosaccharide supplementation. The cold or flu SI score was affected by galactooligosaccharides and stress (P < 0.0001); 2.5 g was associated with a lower SI score across all levels of stress, but 5.0 g was protective only at lower levels of stress. The percentage of days with cold or flu was associated with galactooligosaccharides within different body mass index categories (P = 0.0002), wherein a 40% reduction in the percentage of days with cold or flu was observed in normal-weight individuals with 5.0 g galactooligosaccharides. This effect was not observed in overweight or obese individuals. CONCLUSIONS: Acute psychological stress was directly related to symptoms of gastrointestinal dysfunction and cold or flu. Galactooligosaccharide supplementation reduced these symptoms and the number of days with cold or flu. This trial was registered at clinicaltrials.gov as NCT01137760.

BACKGROUND: Respiratory virus infections are important causes of morbidity and mortality after hematopoietic cell transplantation. Their clinical course can be severe with progression to lower respiratory tract infection, co-infection with serious pulmonary co-pathogens, and high mortality. Non-myeloablative conditioning regimens achieve engraftment without eradication of host hematopoietic cells, which potentially allows for protection against infections commonly seen in hematopoietic cell transplantation patients treated with standard intensity conditioning regimens. DESIGN AND METHODS: We performed a retrospective cohort study to measure the incidence and severity of parainfluenza types 1-4, influenza (A and B), respiratory syncitial virus and human rhinovirus disease in myeloablative versus non-myeloablative versus autologous hematopoietic cell transplantation patients. RESULTS: The incidences of all respiratory virus infections were similar in the non-myeloablative and myeloablative cohorts but less in the autologous cohort (33/420 [7.9%], 150/1593 [9.4%], and 37/751 [4.9%], respectively, p<0.0001). However, respiratory virus lower tract infections were significantly less common during the first 100 days after transplantation in non-myeloablative patients compared to myeloablative and autologous patients (1/420 [0.2%], 34/1593 [2.1%] and 16/751 [2.1%], respectively, p=0.005. Respiratory virus lower tract infection had high co-infection and attributable mortality rates. CONCLUSIONS: Respiratory virus lower tract infection during the first 100 days after hematopoietic cell transplantation was less common in persons receiving non-myeloablative conditioning regimens compared to myeloablative conditioning, despite a similar overall rate of acquisition.

OBJECTIVES: Most previous studies on the association between moisture or mold problems in the home and respiratory symptoms in children were cross-sectional and based on self-reported exposure. The aim of this study was to evaluate the impact of objectively observed moisture damage and visible mold in the homes on early-life respiratory morbidity and atopic sensitization in a birth cohort. METHODS: Building inspection was performed by building engineers in the homes of 396 children, and the children were followed up with questionnaires from birth to the age of 18 months. Specific immunoglobulin E levels were measured at the age of 1 year. RESULTS: Doctor-diagnosed wheezing was associated with the severity of moisture damage in the kitchen and with visible mold in the main living area and especially in the bedroom of the child. The risk for parent-reported wheezing apart from cold increased with the severity of moisture damage in the kitchen. Moisture damage in the bathrooms or other interior spaces had no significant association with wheezing. No significant associations were observed for other end points, such as cough, or respiratory infections. There was a suggestion for an increased risk for sensitization to cat dander linked with moisture and mold exposure. CONCLUSIONS: This birth-cohort study supports previous observations that moisture mold problems in the kitchen and in the main living area increase the risk for wheezing in early childhood. The results underline the importance of assessing separately the health effects of moisture and mold problems in different areas of the home.
